This invention relates to improvements in foam generating tanks.

A further object of this invention is to provide a tank in which one chemical solutionis carried in an outer container, andV another chemical solution is carried in an 4inner pivotallyv mounted container, the contents of which may be readily discharged into the'outer 4container by partially rotating the inner container. Y

A further object of the linvention is to provide a foam generatingftank having an inner container formed with a normally upturned spout portion, and to provide means forv sealing the spout when thetank is notk in use, and means for reversing Vthe position yof the spout when the contentsy of the inner container is to be' discharged intothe outer Y container to produce the desired chemical'reaction.. e Y l With the above main and other incidental objects-in view, the invention consists of the improved foam ygenerating tank and all Y its parts and combinations as set forth in the claims, and all-equivalents thereof.

The accompanying drawing shows a longitudinal section ofjthe improved foam gen-Y erating tank, ypart yof-fth'e inner container section.

Vbeing shown in full and part being'l shown in designates the outer container Which'is 'prosertion or removal' 'of the inner container, in

to. This opening is provided to permit incase it' is desired to replace 'it or tojclean with a medial socket 6. .The outer container is provided at itsA other end witha smaller threaded collar'arranged to receive a cap y8.

" The cap is formed with aV central opening 9A forreceiving a shaftr V10. Said shaftisprovided with a handle 10. The outer container Y also has a. threaded collar. onv its upper portion toV form a fillingopeningjil.l A` filling opening cap 12 is threaded on the collar. vAt

one end of the tankfisy anoutlet pipe 13 to whichis connected valve mechanism 14;, andr 'a hose Airelieffvalve provided with Y.

The inner Container. 211e iS `@r1indrical. -rl a shapeand is formed-iat one end with a normally upwardspout 'p ortio nf22.` At its yother end the container has projecting pin 23 pivot vthe inner container. lAt the spout end ofthe container, the shaft 10 is fiXedly see cured as at 24. The shaft, which revolves in ashaft receiving tube 25, causesthe inner Vwhich rests in the socket 6 of the cap 5 to container to reverse its position and to dis-l Avalve 26, closes or opensthe kopening 27 f the spout 22.Y The valve is operated by a threaded stem Vwhich vextends .through a threaded collar portion 29 projecting from'V charge itsl contents into the outer container."y

the filling opening cap 12, and isoperated by a crank handle28f. A nut 30 is also threaded to the stein above the collar portion and is 'adapted to be locked to the collar by a bolt 31; A- washer `32 is positioned between the nutBO and the Vcollar portion-29..

Y To prepare the tank yfor operation, the inner containeris 'first filled with one chemiy cal solution, and the outer container isjfilled with another'.` The cap '12 isfthen placedv on to seal the outercontai'ner, and the crank 28 is turned vto causel the valve 26 tojseal the inner container. W henit is desired to op-v erate the tank, the crank 28 is turned upwardly to open the spout'of the innercontainer.A

The crank handlelO is then given one-half a turn, which causes the innerc'ontainer to reverse its position, and to discharge its contents into the outer container. The two, chemicals are. of such al nature ythat when they combine, they expand eleven times, and

generate great' quantitiesY ofy foam. This *foam naturally exerts agreat outward force, (so, that when the valve 14 of the outlet pipe I is opened, the 'foam is forced out through the hose 15.

From the foregoing description, it may be seen that the foam generating tank is simple in construction, is strong and durable, is simple in operation, and iswell adaptedforthe purposedescribed. Y
